Steel Roofing Sheets | Galvalume Grade

Our steel roofing sheets utilize premium galvalume steel substrate - an advanced alloy combining 55% aluminum, 43.4% zinc, and 1.6% silicon for superior corrosion resistance. This AZ55 coating provides up to 4 times the corrosion protection of traditional galvanized steel. Call for steel sheet specifications and pricing tailored to your project.

We stock 22 gauge (0.8mm), 24 gauge (0.6mm), and 26 gauge (0.5mm) steel roofing sheets, each meeting ASTM A792/A792M standards for quality and performance. The galvalume steel coating forms a protective barrier that self-heals minor scratches, providing decades of rust-free performance in harsh Canadian weather including coastal salt spray exposure.

Our steel roofing sheets feature advanced PVDF and SMP paint systems bonded to the galvalume substrate for maximum UV resistance and color retention. The multi-layer coating process includes primers, color coats, and clear top coats, creating a weather-tight barrier that maintains appearance and performance for 30+ years.

Choose galvalume steel roofing sheets for projects demanding superior strength-to-weight ratios, exceptional corrosion resistance, and long-term durability. Our team provides technical specifications, gauge recommendations, and engineering support to ensure you select the optimal steel roofing solution for your application.
